Abstract: To form a paved surface, a laminate is used which has on the bottom a geotextile fabric pith the mesh structure on the top. The fabric is adhered to the road base by spraying or spreading a bituminous liquid onto the base and laying on the laminate and applying further adhesive to the top of the laminate; asphalt is then placed and rolled. The laminate is formed of a square or rectangular mesh structure which has oriented stands connected at junctions which are thicker than the strands and have low orientated or unorientated nodules. On one side the surfers of the nodules are melted and the fabric is pressed into the nodules so that the plastics material of the nodules envelopes some of the fibres or filaments of the fabric to form a mechanical bond, In this way, the oriented strands stand proud of the fabric, to enable the asphalt aggregate to penetrate into the meshes and interlock with the strands.

Title: Dry filter for the treatment of water
Inventor: FRICK BERND
IPC: C02F3/04
Filed: 1989-11-23
Abstract: (Translation) Dry filter for the treatment of water Abstract:         Subject matter of the present invention is a dry filter for the treatment of water comprising an unsubmerged filter bed (16), the water to be treated trickling onto its exposed surface (18).  The danger thereby exists that the impacting water will smash the material of the filter bed to pieces with the result that the destroyed material obstructs the exposed surface (18) of the filter bed (16) which leads to overdamming and to the cut-off of the air supply in biofilters.  To avoid these disadvantages the exposed surface (18) of the filter bed (16) is covered with a layer of impact resistant balls (20), for example of plastic, which float during backwashing of the filter bed.         The advantage of this solution is that the falling water is dispersed before impact by means of the balls (20), the water deflected off these balls seeping between them into the filter bed (16), thereby ruling out destruction of its exposed surface (18).

Abstract: Computer Controlled Adaptive Speakerphone Abstract An improved switched-loss, adaptive speakerphone dynamically adjusts its switching thresholds and other performance parameters based on an analysis of acoustic environment and telephone line conditions. To access these conditions, the speakerphone utilizes a computer with sssociated firmware. As part of a calibration process, the speakerphone computes its thresholds before each use to compensate for possible variations in hardware circuitry therein. This is achieved by passing a first and then a second level of a test tone signal through the hardware circuitry and measuring the resulting response. The speakerphone also measures the acoustics of the room in which it operates as part of the calibration process. For this measurement, a tone burst signal is generated through a loudspeaker in the speakerphone and measured by a microphone also in the speakerphone. A time-domain acoustic response of the room is obtained which provides to the computer the amplitude of the return signal and the duration of its echo. The calibrationprocess is also applied to the speakerphone's interface to the telephone line through a hybrid. While in use, the degree of hybrid reflection is measured and the result provided to the computer. With the information on both the acoustic environment and the hybride the adaptive speakerphone is able to adjust on a real time basis the amount of switched loss and threshold switching levels between operating states to suit existing conditions. If, for example, the speakerphone is attached to a good telephone line and is in a good acoustic environment, it will provide the user with near full to full duplex performance.

Abstract: REGISTER AND ARITHMETIC LOGIC UNIT       ABSTRACT Register and arithmetic logic apparatus for use in processing digital data and which provides a split pipeline architecture that operates on multiple data formals. A register file (444) is employed to store data words. An arithmetic logic unit (450) processes the data words by means of two parallel arithmetic logic units (450a, 450b) that provide fixed point and floating point arithmetic processing operations, respec-tively. The two parallel arithmetic logic units (450a, 450b) permit processing of a plurality of predetermined data processing formats, including dual 16 bit fixed point, 32 bit fixed point, 32 bit floating point and logical data processing formats. Post-pro-cessing registers (454, 456) provide for a limiter/shifter register, a length selectable first in, first out buffer for controlling the length of the register pipeline, and logic which provides for queuing of the processed data words. The register file (444) and the fixed point arithmetic logic unit (450a) may be selectively coupled together to function as an accumulator. This function permits processing of the data words such that two 32 bit data words are accumulated into a 64 bit data word, or the dual 16 bit data words are accumulated into two 32 bit data words. Processing using the dual 16 bit format employs a potential overflow scheme that permits a variety of gignal pro-cessing algorithms to function with relatively compact code.

Abstract: A word serial multiplier includes a first circuit loop for loading a parallel-bit multiplier, and in response to a clock signal sequentially produces a gate signal corresponding to a sequence of bits of the multiplier sample in descending order of significance. A second circuit loop loads a multiplicand sample and in response to the clock signal successively divides the multiplicand sample by the factor two. The more significant bits, exclusive of the least significant bit, of the divided multiplicand sample are coupled to a gating circuit. The gating circuit passes the more significant bits to the input of an accumulator if the corresponding bits of the gate signal exhibit a predetermined state. After a number of cycles of the clock signal, corresponding to the number of bits m of the multiplier sample, the accumulator produces a scaled product equal to the multiplicand times the multiplier times the scale factor of 2-(m-1).

Abstract: A data processing system and method of operation which substantially reduces the time lost in unnecessarily checking for the presence of all memory references required by a special section of code in an operating system before the program is run and which dynamically protect the program requiring the memory reference from crashing if the memory reference is not presently available.  The method assumes that all memory references are available and begins running the special section of code.  If a request is made for information not in assigned memory storage, the data processing system interrupts the running of the special section of code and undoes everything the special section of code has done prior to the interrupt.  The requested memory reference is then located in storage.  The information is retrieved and written into assigned memory.  The special section of code is then restarted and supplied the needed information.   It has been found that it takes much less time to assume the memory references will succeed and occasionally interrupt, erase and restart, than to make a time-consuming preliminary check for all memory references.

Title: Firefighters barrier penetrator and agent injector
Inventor: MCCLENAHAN CHARLES H
IPC: A62C31/22
Filed: 1990-11-15
Abstract: A penetrator for a fire extinguishing tool has an impact end and a striker end. The penetrator has an impact barrel having a central axis, an axially-extending internal wall, a striker end and an impact end. An axially-extending nozzle having an axially-extending passage barrel is slidably placed in the impact barrel, the nozzle barrel having a peripheral wall with nozzle ports therethrough. A point attached to the nozzle barrel, projects beyond the impact barrel, and a shoulder on the point is laterally aligned with the impact end of the impact barrel for transmission of impact forces from the impact barrel to the point. A first socket is formed in the point facing into the passage in the nozzle barrel, and a taper in the socket narrows toward the impact end. An end cap on the impact barrel at its striker end closes the impact barrel, and has an axially extending rod passage therethrough. A second socket formed on the end cap faces into the impact barrel, and a taper in the end cap enlarges as it extends into the impact barrel. A slide rod is slidably fitted in the end cap, and a collar on the rod outside of the impact barrel. A retainer is attached to the slide rod inside the impact barrel, a first taper on the retainer facing toward the first socket, and a second taper on the retainer facing toward the second socket. A slide hammer is reciprocably slidably fitted on said slide rod and has a striker face disposed and arranged so as to be impacted on the striker surface of the impact barrel. Retention means on the barrels prevent the nozzle barrel from being expelled from the impact barrel. Inlet port means through the impact barrel admits fluid under pressure into the barrels. With the first taper in the first socket, much of the slide rod is held inside the impact barrel, and with the second taper in the second socket much of the slide rod is held outside of the impact barrel.      Impact of the slide hammer on the impact barrel exerts forces on the structure through the point. After penetration, fluid under pressure will be admitted to the barrels, thereby extending the nozzle barrel, and exposing the nozzle ports in order to inject fluid agent into the structure.
